Conduction
Consistently long PR interval.
First drug of choice for v-tach or v-fib.
First component of wave form.
What is hypovolemia,hypoxia,hydrogen ion (acidosis),hypo/hyperkalemia, hypoglycemia, hypothermia, toxins, cardiac tamponade, tension pneumothorax,thrombosis (coronary or pulmonary) trauma?
Extends from the Bundle Branches into the Endocardium and into the myocardial tissue.
What is purkinje fibers?
Irregularily irregular
When reviewing ACLS...name a rhythm that you do not shock.
What is asystole?
Follows the P wave and represents depolarization of the ventricles.
Rhythm that puts patients at risk for stroke.
Main function is to delay impulses by 0.04 secounds to keep the ventricles from contraction too quickly.
P-R interval is long, longer, longer, until you drop a QRS complex
What is Wenckebach? 2nd degree type 1
Initial bolus: 300 mg IV
Represents ventricular recovery or repolarization.
Valves are open when the ventricles contract.
Located between left & right bundle branches and AV node.
No relationship between the P-R and QRS complexes.
What is Third Degree Heart Block (complete)?
6 mg IV push over 1-3 seconds.
Represents the end of ventricular conduction and the beginning of recovery; a change may indicate MI
You deliver a shock in a controlled setting and it is timed NOT TO interrupt the T wave of the preceding beat.
What is Synchronized Cardioversion?
Please state the correct path of electricle impulses through the heart.
What is SA,AV,Bundle of His, Bundle Branches, Purkinje Fibers?
You can see an organized rhythm but feel no pulse.
What is PEA (pulseless electrical activity)?
Dose is 2-10 mcg/kg/min.
This is when the pacemaker fires when it should, but we only see a spike on the EKG strip without a response
